1 Land contracts or contracts for deed are a security agreement between a seller, called a Vendor, and a buyer, called a Vendee.  The Vendor agrees to sell a property by financing the purchase for the Vendee.
The two DNA strands are held together by interchain hydrogen bonds. H-bonds pair the bases in one chain to the complementary bases in the other chain. (A/T and G/C).
The information is carried in only one of the two strands of DNA, which is called the coding strand. Every nucleotide in the coding strand has a complementary nucleotide in the other strand, called the template strand. The Watson-Crick pairs are the standard DNA and RNA base pairs. In DNA, adenine bonds to thymine while guanine bonds with cytosine. The same pairs apply to RNA, except that uracil replaces thymine.
